ABSTRACT Sleep quality plays an important role in maintaining cognitive functions, particularly decision-making, which is essential for medical students. This study aimed to analyze the relationship between sleep quality and decision-making among students of the Medical Education Program, Faculty of Medicine, Syiah Kuala University, class of 2022. This study was a quantitative analytic study with a cross-sectional design conducted from October to December 2025, involving 138 respondents selected using consecutive sampling. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), while decisionmaking was assessed using the Decision Making Questionnaire Guide, which includes the dimensions of intuitive, principled, optimization, social resistance, indecisiveness, control, and thoroughness. Data analysis was performed using univariate and bivariate analyses with the Chi-Square test at a 95% confidence level. The results showed that the majority of respondents had poor sleep quality (66.7%). There was a significant relationship between sleep quality and all dimensions of decision-making, including intuitive, principled, optimization, social resistance, indecisiveness, control, and thoroughness (p < 0.05). Students with good sleep quality tended to demonstrate more optimal and thorough decision-making compared to those with poor sleep quality. In conclusion, sleep quality is significantly associated with decision-making among medical students; therefore, efforts to improve sleep quality should be considered to support students’ academic and professional performance.
